A Dictionary of Greek and Roman biography and mythology

5. The elder of the two daughters of M. Antonius by Octavia, the sister of Augustus, was born B. C. 39, and was married to L. Domitius Ahenobarbus, Cos.. B. C. 16. Her son by this marriage, Cn. Domitius, was the father of the emperor Nero. [See the Stemma, p. 84.] According to Tacitus (Tac. Ann. 4.44, 12.64), this Antonia was the younger daughter; but we have followed Suetonius (Suet. Nero 5) and Plutarch (Plut. Ant. 87) in calling her the elder. (Compare D. C. 51.15.)
